I use TCs and tubes behind my macros for extra mag, I gave up using reversed 
lenses years ago, it's just far too clumsy and undertaking especially in the 
field. I am surprised by the John Shaw comment though, I would have assumed 
that low distortion lenses would give better results particularly in the case 
of CA and spherically induced coma etc.
